pass api client instance in as parameter
move all() and create() methods to userservice

remove static references to ApiClient
remove static reference
permissions is now a service, uses non-static api client
also pass api instance to local user
make nodeservice responsible for loading log levels

this avoids creating yet another service, and since this is tied to a node anyway it's fitting.
could possibly also go into Node itself
do what i said in the last commit ;)

move allLoggers to Node, we already do that for other things
de-staticize remaining ApiClient.get calls

moved lots of stuff to ClusterService, we need to reorganize some of this later.
